Answer: B. Its magnetic power will increase.

The correct answer is B. Its magnetic power will increase.
An electromagnet's strength is directly proportional to the electric current.
Increasing the flow of electricity creates a more intense magnetic field.
This allows the magnet to pull or lift heavier objects than before.
Conversely, reducing the current makes the magnetic power weaker.
If the current is switched off completely, the magnetism disappears.
